GEARING FOR \VA$HING'MACHINES.

Specification of Letters Patent.

Patented Sept. 23, 11929.

Application filed September 28, 1908. Serial No. 455,114.

To all whom it may concern:

lie it known that I, WILLIAM RUTHYEN, a citizen of the United States, and a resident of Chicago, in the county of Cook and State ofIllinois, have invented certain new and useful Improvements in Gearing for \Vashing-Machines, of which the following is a full, clear, and exact specification.

My invention is concerned with a novel mechanism primarily designed for transforming the swinging movement of the operating lever of a washing machine into the reciprocating rotary movement of the stirrer or heater shaft and the continuoushighspeed rotary movement of the fly wheel associated therewith to give evenness and ease of operation to such machines despite the reciprocating movement of the main parts thereof.

To illustrate my invention, 1 annex hereto a sheet of drawings, in which the same ref erence characters are used to designate identical parts in all the figures, of which,

Figure 1 is a top plan view of a machine embodying my invention; Fig. 2 is a side elevation of the same; andFig. 3 is a detail .as by the screws or bolts 16.

view in section on the line A-A of Figs. 1 and 2.

My invention is adapted to be employed in connection with a tub 10 of the ordinary construction, which is supported at a suitable height by legs, not shown, and which has the lid 11 hinged thereto, as at 12, and the entire gearing is preferably carried by said lid, so that when it is raised the gearing moves with it. The beater shaft, the upper end of which is indicated in dotted lines at 13, is journaled in the bearing indicated by dotted lines at 14, formed near the inner end of the bearing casting 15, which is secured to the lid in any suitable manner, This beater shaft carries on, the upper end the pinion 17, likewise indicated in dotted lines in Fig. 1.

'lhehandle lSis secured in the socket 19 of the lever casting 20, whichhas the bearing aperture by which the lever is mounted to swing on the bearingpin 21 projecting hori zontally from one corner of the casting 15, This lever casting 20 has projecting downwardly therefrom the arm 22 carrying the eccentric pin 23, which has the link 24- pivoted thereon at one end, the other end of said link being pivoted upon the eccentric bearing pin 25secnred to the gear wheel 26,

which is mounted on the horizontal bearing pin 27 projecting from the end of the cast cured thereto or formed integrally therewith the pinion 30, which meshes with the gear wheel 26, so that as the handle or lever 18 is swung, the fly wheel 29 will be rotated at a high rate of speed to furnish the necessary momentum for an even and easy operation of the machine. The lever casting 20 likewise has formed thereon, opposite to the arm 22, anotherarm 31, which contains a bearing socket '32, the arm 31 being at the proper angle to the bearing stud 23, and the socket 32 being set at the proper angle in the arm 31 so that it can cooperate with the bearing pin 33 extending into the socket and carried by the jointed portion 34 of a lever which is pivoted on a bearing stud projecting vertically upward from the frame casting 15. This jointed lei'cr consists of the outer jointed portion 3%, which has the i yoke-shaped-inner end 36 by which it is pivoted upon the pin 37 passing through the sqnai'edsocket 38 of the portion of the lever that has no vertical movement. This lastmcntioned portion 39 of the lever extends to the center of the machine, and is provided with the segmental teeth 40, indicated in dotted lines in Fig. 1, which are preferably located beyond the pinion 17 with which the teeth engage, and a downwardly projecting flange etl, indicated by dotted lines in Fig. 1, is preferably provided to strengthen the portion 39 of the love and inclose the meshing teeth, so that there is no danger of anything being caught therein.

The operation of the complete apparatus will be readily apparent, as it will be seen that when the lever 18 is reriprocated, the link connections with the spur go: and the iiy wheel 29 will cause tl utter to be rotated at 'a high rate of speed, and at each reciprocation of the lever 18, the jointed arm 34 of the jointed. lever will swing through a curved are made up by the horizontal movementuponthe bearing stud 35 and the vertical movement on the bearing stud 37, which vertical movement, of course, is necessary to accommodate the rising and falling of the position of the socket 32 as the lever 18 is reciprocated. The portion 39 of the jointed lever, of course, is swung through heel 26 a gear wheel pivoted on the pin said pinion, r:

eciproca for a proper angle, and causes the in the cos with the 1 o l, a mission lCYt J pi oted on the pin 35} 21nd having gear teeth at his inner end in shing with the pinion, and the. jointed arm at; its outer end having a. pin 33 engaging the socket 3:3.
